28 Proven Ways to Promote the Regeneration of Myelin

This article was originally published in 2017 and has been regularly updated to reflect new research

Myelin is critical for optimal brain function and mental health.

What is myelin?

Myelin is a fatty, white substance that wraps around the end of many nerve cells. It forms an electrically insulating sheath that increases nerve condition speeds.

In other words, it allows your brain to send information faster and more efficiently, making it absolutely essential for the optimal functioning of your nervous system (39, 40). 

So not surprisingly, myelin sheath plays a key role in determining intelligence and improving cognitive performance (41, 42). 

The production of myelin throughout the nervous system is called myelination or myelinogenesis.

But demyelination can also happen. 

This happens when the myelin that insulates your nerves is destroyed or deteriorates, leading to mental health symptoms and neurodegenerative diseases (44). 

Multiple sclerosis is one of the more common demyelinating condition, but a number of neurological and psychiatric illnesses have been linked to demyelination, including (45):

• Attention deficit hyperactivity disorder

• Depression

• Bipolar disorder

• Dyslexia

• Language disorders

• Stuttering

• Autism

• Obsessive-compulsive disorder

• Cognitive decline

• Alzheimer’s disease

• Tourette’s syndrome

• Schizophrenia

• Tone deafness

• Pathological lying

If you have one of these conditions and suspect you might have symptoms of demyelination, don’t worry.

There are dietary and lifestyle modifications that can help your body repair and re-manufacture myelin. Studies show that oligodendrocyte cells are responsible for the formation of new myelin in both the injured and normal adult brains (43).

Here are 28 holistic ways to increase oligodendrocyte cells, promote myelin production and myelin sheath repair, and increase the regeneration of myelin. 

1. Deep Sleep and Melatonin

Research has found that sleep increases myelination and increases the production of oligodendrocyte precursor cells (OPCs).

One study found that production of OPCs doubled in mice while they slept. The mice that were forced to stay awake had higher levels of stress hormones and higher rates of brain cell death (1-2). 

Researchers believe this means that sleep loss can aggravate symptoms of multiple sclerosis.

That’s why getting at least 7 hours of high-quality, restorative sleep is so critical. 

But it’s not just the amount of sleep you get that’s important. It’s also the quality of your sleep. 

The researchers found that the production of the myelin-forming cells increased the most during deep, rapid-eye movement (REM) sleep. 

Melatonin, your body’s sleep hormone, has also been shown to promote myelination and increase myelin production by significantly reducing inflammation in the brain (46).

This supplement contains magnesium and a number of other natural compounds that I’ve used over the years to promote the production of melatonin.

But I work with my clients so that they can naturally produce more melatonin and maximize the quality of their sleep without so many supplements. We have free online workshop that talks about how you can work with us. You can register for the workshop here.

Deep sleep can also improve your brain’s growth hormone, lower your stress hormone, and slow down the onset of dementia. 

2. Iodine and Thyroid Hormones

Iodine is a key mineral that is required to produce thyroid hormones. Without enough iodine, you may end up with symptoms of hypothyroidism. 

Research shows that a deficiency in iodine and lack of thyroid hormones can impair myelination (7).

“The process of myelination is known to depend on the thyroid hormone. The myelinating cells are the oligodendroglia which appear to stop functioning in MS (and sometimes to a milder degree in Alzheimer’s disease, and other conditions). The cells’ absorption of thyroid hormone is influenced by dietary factors.”

— Ray Peat

Other studies show that thyroid hormones stimulate the expression of myelin protein genes, and promote remyelination in the brain by enhancing oligodendrocyte maturation (8, 9). 

So supporting your thyroid and getting enough iodine are key steps towards increasing myelin and optimizing the formation of new myelin. 

You can read more about how to support your thyroid and enhance the production of thyroid hormones here.  

I highly recommend getting a full thyroid panel done regularly.

3. Vitamin C

Vitamin C is known to participate in myelin formation (10, 11). 

Collagen synthesis, which is dependent on Vitamin C, has also been linked to the formation of myelin sheath (12, 13). 

Vitamin C can be found in foods such as peppers, citrus fruits, green leafy vegetables, broccoli, tomatoes, and berries. These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

You can also take it in supplement form. 
 

4. Zinc

As I’ve discussed before, zinc is an essential trace mineral that activates several hundred enzymatic reactions, including neurotransmission.

It’s estimated that 2 billion people in the world are deficient in zinc, and six different studies show that subclinical deficiency of zinc impairs brain function in children and adults (14-16).

So, if you struggle with a brain or mental health disorder, it’s quite possible that you’re deficient.  

Zinc also affects myelination.

The mineral is needed for myelin proteins to work properly, and research shows that a deficiency in zinc leads to a reduction in myelin formation and myelin recovery (17). 

Some of the best food sources of zinc include oysters, grass-fed beef, pumpkin seeds, cashews, mushrooms and spinach. These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

But I still recommend at least short-term supplementation to ensure you get enough to increase myelination.

That’s why I created the Optimal Zinc supplement. 

Check out my previous post about zinc and copper if you’re interested in discovering more steps you can take to increase your zinc levels.  

5. Cholesterol

Cholesterol is a waxy, fat-like substance that’s found in all cells of the body.

Your body needs cholesterol to make hormones and vitamin D.

And it’s an indispensable component of myelin. 

Without it, myelin membrane growth is “severely perturbed” (18). 

So just like you shouldn’t be afraid of saturated fat, you shouldn’t be afraid of eating cholesterol-rich foods.

Some of the best sources of cholesterol include grass-fed butter or ghee, beef liver and pastured egg yolks. These foods are included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.

6. Lithium 

Lithium is predominantly known as a medication given to bipolar patients to manage their symptoms. 

However, it’s also an essential mineral.

Bipolar patients are often given high doses of lithium carbonate.

But low doses of lithium orotate can be safely supplemented to support the brain and improve mental health.

Research shows that lithium stimulates the expression of myelin genes, restores the myelin structure, and promotes remyelination (19). 

As I discussed before, lithium orotate can also increase your brain’s growth hormone (BDNF). 

So it’s definitely something you want to consider taking if you want to increase myelin in the brain.

7. Oxygen Therapy

Hyperbaric oxygen therapy (HBOT) is a treatment that enhances healing and recovery after injury to the central nervous system.

Patients inhale 100% oxygen in a total body chamber. 

Usually, oxygen is transported throughout the body only by red blood cells. But with HBOT, oxygen is dissolved into all body fluids, including the fluids of the central nervous system.

This leads to oxygen being  carried to areas of the body where circulation is diminished or blocked. As a result, extra oxygen can reach all damaged tissues, including areas that need to heal.

Researchers have found that HBOT can cause "significant remyelination" (83-84). 

Other studies show that it can alleviate myelin damage (85). 

You’ll need to find a practitioner or clinic in your area that provides this treatment.

8. Ketogenic Dieting

A ketogenic diet is a very low-carb diet – less than 50 grams of carbs per day.

When you restrict carbohydrate-rich foods – such as grains, sugar, and even potatoes, legumes and fruit – your body enters ketosis, a metabolic state in which your body and brain run on fatty acids and “ketones” instead of glucose.

Ketones are an alternative source of energy for your brain cells. And several studies show that when you increase the production of ketones, you improve myelination and increase myelin production (3-6). 

So if you’re trying to rebuild myelin sheath, you should consider a cyclic ketogenic diet. 

As I’ve discussed before, ketones can also increase your brain’s growth hormone, help you overcome brain fog, support your brain’s mitochondria, and slow down cognitive decline. 

9. Iron

Iron is an essential mineral that is present in all cells and plays a role in several vital functions, including oxygen consumption and ATP production.

It’s also important for myelin production.

Studies show that low iron levels lead to a reduction in myelination, and normal iron levels support the formation of myelin and increase myelin (20). 

Beef liver is one of the best sources of iron, and it’s included in my Free Grocery Shopping Guide for Optimal Brain and Mental Health.
 

10. Low Level Laser Therapy

Low-level laser therapy (LLLT), or photobiomodulation, is a treatment that uses low-level (low-power) lasers or light-emitting diodes (LEDs) to stimulate brain cells, helping them function better.

Most doctors don't know about LLLT; but not every doctor.

Dr. Norman Doidge, a physician who teaches at the University of Toronto here in Canada, discusses the amazing effects of LLLT in his book The Brain’s Way of Healing.

Researchers have found that LLLT can increase myelination and increase the total number of myelinated axons (79-81). 

LLLT has also been shown to restore normal levels of myelin in animals (81-82). 

I previously wrote about my experience with low-level laser therapy here.

You can use this device and shine the red and infrared light on your forehead for 5 minutes every day. I also shine it on other parts of my head and on my entire body, including on my thyroid, thymus gland and gut. I have experienced incredible benefits from doing this.

Alternatively, you can use this smaller and more convenient device and shine it on your forehead.

You can also use the Vielight Neuro Duo, which is a transcranial-intranasal headset with 810 nm of near infrared light. It penetrates deeper into brain tissue and is absorbed better by the central nervous system. If you decide to try a Vielight device, you can use the coupon code JORDANFALLIS for a 10% discount

LLLT also supports mitochondria function, reduces brain fog, promotes synaptogenesis, and increases blood flow to the brain. 

I encourage you to check out my full article about it for more information.

11. Phosphatidylserine

Phosphatidylserine is a fat-soluble amino acid compound that plays a key role in optimal cognitive function. High amounts of phosphatidylserine can be found within the brain, and supplementation has been shown to improve attention and memory, especially in the elderly (21-23).

“…consumption of phosphatidylserine may reduce the risk of dementia and cognitive dysfunction in the elderly.”

— Food and Drug Administration

Researchers have also concluded that phosphatidylserine is required for healthy nerve cell membranes and myelin in the brain (24). 

That’s why phosphatidylserine is part of the Optimal Brain supplement. 

Make sure you read this article to learn more about the remarkable benefits of Phosphatidylserine.

12. Pregnenolone

Pregnenolone is a steroidal hormone manufactured by the body, but it can also be taken as a supplement.

It’s been shown to enhance memory and reduce stress-induced fatigue.

It’s the precursor to almost all other steroid hormones, including DHEA, progesterone, testosterone, estrogens, and cortisol.

Pregnenolone and other steroid hormones regulate, repair, rebuild, and increase the production of myelin (25-28). 

I personally tried pregnenolone. It did give me a boost in brain function and mental energy. However, it also made me angry and irritable so I stopped taking it. This happens to some people, but a lot of people don't experience this. It's worth trying to see how you react.

13. Uridine 

Uridine is a nucleotide base found in beer.

I don’t recommend drinking beer, but supplementing with pure uridine can protect the brain, enhance cognition, and increase mood and motivation. 

It’s been proven to help treat “myelin sheath lesion” in several experimental and clinical studies (29, 30). 

14. Herbs That Increase Myelin

Ashwagandha is a popular Indian herb commonly used to prevent anxiety.

Withanoside IV is one of the main therapeutic compounds in ashwagandha and research shows that it can increase myelin levels in the nervous system (31).

I have taken ashwagandha during periods of high stress. It’s included in this supplement.

Ginkgo Biloba is another common herb, which is taken for cognitive enhancement or to alleviate cognitive decline.

It’s beneficial effects of cognition may be because it significantly increases the number of myelinated axons (34).  

Ginkgo Biloba is included in the Optimal Brain supplement. 

15. Inositol

Inositol is a small molecule structurally similar to glucose that is involved in cellular signalling. 

At high doses, it reduces anxiety. 

Research shows that animals treated with inositol have significantly fewer demyelinating lesions (32). 

I took high doses of inositol powder when weening off psychiatric medication.

I previously wrote a full article about inositol here. 

16. Lion’s Mane 

Hericium Erinaceus – better known as Lion’s mane mushroom – might be my favourite way to regenerate myelin. 

Research shows that lion’s mane increases the rate of myelination production, and the process of myelination begins earlier in the presence of the mushroom (33). 

I used to take this lion’s mane mushroom. It’s one of the highest-quality lion’s mane mushroom supplements that I could find from a reputable brand. I spent a lot of time researching and looking into different sources because not all lion's mane supplements are high-quality and effective, and I settled on this one.

17. Consume Flavonoids

There are several flavonoids, a diverse group of phytonutrients found in fruits and vegetables, that have been demonstrated to promote myelination. 

Research shows that the flavonoids luteolin, quercetin and fisetin significantly decrease myelin phagocytosis and may be able to limit the demyelination process during multiple sclerosis (35). 

Quercetin, one plant flavonoid in particular with potent antioxidant action, has been shown to increase the number of oligodendrocyte precursor cells and myelin basic protein cells (36). 

18. Learn or Experience Something New

You can also generate new myelin by learning something new and exposing yourself to novel life experiences.

For example, one report showed that learning a new instrument leads to increased myelin in areas of the brain involved with musical performance. 

The researchers explain that myelin increased proportionately to the number of hours each person had practiced the instrument (38).

So the more you practice and try to learn something, the more myelin you generate.

19. Exercise

I’ve already discussed how exercise increases your brain’s growth hormone, supports your brain’s mitochondria, helps reverse cognitive decline, and stimulates your vagus nerve.

It clearly does so much good, so it’s not too surprising that it also supports myelin formation. 

Research shows that long-term exercise improves memory by increasing and restoring myelin (47). 

Running has also been shown to increase myelination and delay the progression of demyelination, and therefore delays the progression of Alzheimer’s disease (48). 

Lastly, researchers have found that exercise increases mitochondrial activity, which then increases myelination in the brain (49). 

This is exercise routine I try to follow consistently:

• Lift heavy weights 1-4 times per week

• High-intensity interval sprinting 1-2 times per week

• Walk as much as I can (ideally 30-60 minutes every day)

• Walking, weightlifting and sprinting are the best forms of exercise, but you should choose a sport or exercise routine that you enjoy, so that you’ll stick with it consistently

20. Brain-Derived Neurotrophic Factor (BDNF)

Brain-derived neurotrophic factor, also known as BDNF, is a naturally-occurring hormone in the brain that improves brain function and lowers your risk of mental disease. 

It also regulates the myelination process. 

Research shows that BDNF produces a long-term increase in both the rate and extent of myelination, and enhances and accelerates myelin formation (50). 

I previously provided 31 ways to boost BDNF in this post.  

21. Testosterone

When I lived in a moldy home, suffered multiple concussions and was placed on antidepressants, my testosterone plummeted. 

No conventional doctor tested my testosterone because they assumed every a man in his 20s would have healthy levels. 

But they were wrong. 

Eventually I saw a smart doctor and he found out that I had the testosterone levels of an old man.

I was put on testosterone replacement therapy for almost one year to get my levels back to normal. And over that time, I saw a huge increase in my brain and mental health.

This may be because testosterone has been shown to stimulate the formation of new myelin and reverse myelin damage (51). 

Researchers have also concluded that hormone replacement should be a considered treatment for males who have multiple sclerosis, as it can stall (and perhaps even reverse) the neurodegeneration associated with MS (52). 

That's why it's so important to test. Make sure you check both total testosterone and free testosterone. 

You can test your total and free levels here. 

22. Omega-3 Fatty Acids

Omega-3 fatty acids are essential fats that your body cannot produce itself. They are found primarily in fish and are necessary for the normal electrical functioning of your brain and nervous system.

They appear in most of my posts because they are so critical for brain and mental health and affect so many aspects of wellness.

They’ve been shown to help people overcome addiction, repair the blood-brain barrier, stimulate the vagus nerve, and even reverse cognitive decline.

And now researchers have found that they also increase myelin production, helping your body produce more myelin (53, 54). 

According to Judy Graham, author of the book Managing Multiple Sclerosis Naturally: A Self-Help Guide to Living with MS, myelin cell membranes that contain omega-3 fatty acids are more fluid, which improves the efficiency of nerve impulse conduction. 

She also points out in her book that rates of multiple sclerosis are lower in areas of high fish consumption. 

I eat lots of wild salmon and sometimes supplement with krill oil.

23. Vitamin D and Vitamin K2

Vitamin D is a fat-soluble vitamin that our skin synthesizes when exposed to the sun.

Research shows that the Vitamin D receptor boosts the regeneration of myelin (55). 

Vitamin D also significantly increases myelination in rats (56). 

It’s best to get your Vitamin D from sunlight, but most people can’t get enough, especially during the winter. 

That’s why I sometimes take a Vitamin D3 supplement.

If you decide to supplement, it’s a good idea to also take some Vitamin K2 with it, as it has also been shown to support myelin (57). 

I also highly recommend checking your Vitamin D levels. It's one of the most important tests you can take for your health.

24. Choline

Choline is an essential B vitamin that most people don’t consume enough of, because very few foods in the Western diet contain it.

It’s also a component of myelin and supports myelin production.

Research shows that the choline pathway promotes remyelination, and enhances the repairing and rebuilding of myelin sheath (64). 

Citicoline (also known as CDP-Choline) is the most bioavailable form of choline. 

One study found that citicoline enhances myelin regeneration and increases remyelination in the central nervous system. The researchers concluded that citicoline could become a promising substance for patients with multiple sclerosis because of its regenerative action combined with its excellent safety profile (63). 

That’s why I recommend supplementing with it. It’s one of my favourite supplements for optimal brain and mental health. I find it improves my focus and mental energy. It's included in the Optimal Brain supplement. 

You can also find some choline in beef liver and egg yolks, but citicoline is more impactful. 

And as I’ve discussed before, citicoline can also help you overcome brain fog and support the blood brain-barrier.

Make sure you read this article to learn more about the remarkable benefits of Citicoline.

25. Reduce Inflammation 

Reducing inflammation throughout your entire body is a key step towards protecting and regenerating myelin. 

Researchers have found that inflammatory cytokines reduce myelination, and high levels of inflammation are often found in people with multiple sclerosis (65). 

One of the best ways to reduce inflammation is by following an anti-inflammatory diet.

If you decide to follow an anti-inflammatory idet, you should strive to eliminate all gluten, refined carbohydrates (particularly flour), and processed food from your diet, and increase your intake of vegetables, fruits, wild fish, grass-fed beef and pastured chicken.

My free Grocery Shopping Guide for Optimal Brain Health contains a bunch of healthy anti-inflammatory foods that you can eat on a regular basis. 

Taking curcumin and krill oil supplements can also significantly reduce inflammation in the body and brain. 

Make sure you also check out this article for 23 effective ways to reduce inflammation in the brain.

26. B Vitamins and Methylation

A number of different B vitamins can increase myelin and help your body regenerate myelin. 

Vitamin B12 plays a key role in the generation and function of myelin.

Researchers have found that low vitamin B12 levels are significantly associated with myelin degeneration (66, 68). 

Other studies have also shown that people with multiple sclerosis often have abnormally low levels of vitamin B12, and vitamin B12 injections significantly improve their symptoms (67). 

According to Dr. Perlmutter, author of Brain Maker and Grain Brain, vitamin B12 deficiency enhances the destruction of myelin and compromises the ability of the body to repair and rebuild damaged myelin sheath. 

Folate is another B vitamin that plays an important role in the maintenance of myelin. Studies have shown that a deficiency can lead to reduced levels of myelin (69-70). 

S-adenosylmethionine (SAMe) isn’t a B vitamin, but along with folate and B12, it is involved with methylation, and has been shown to increase the development of myelin (71). 

One amazing study found that biotin (Vitamin B7) activates enzymes involved in myelin synthesis and 91% of patients with multiple sclerosis improved with high doses of biotin. Two multi-centric double-blind placebo-controlled trials are currently underway (72). 

Lastly, pantothenic acid (Vitamin B5) can indirectly help with myelin formation because it helps with the synthesis of fatty acids and myelin is mostly made up of fat. Myelin has been shown to degenerate in chickens that are deficient in B5 (73). 

27. Probiotics and Prebiotics

It is estimated that 100 trillion bacteria, and 500 to 1,000 species of bacteria, live in the human gut.

These gut bacteria, collectively known as the gut microbiome, help with digestion.

But an increasing amount of research suggests that gut bacteriaalso communicate with your brain through the microbiome-gut-brain axis.

And probiotics and prebiotics can improve your brain health and support myelin production by actually changing the mixture of bacteria in your gut.

Probiotics are live microorganisms with health benefits when consumed, generally by improving or restoring the gut microbiome.

Meanwhile, prebiotics are substances that humans can't digest, so they pass through our gastrointestinal tract and promote the growth of many different strains of good bacteria in your gut. Essentially, prebiotics are food for the probiotics in your intestines.

Research has found that your gut microbes affect the structure and function of the brain by regulating myelination. Probiotics and prebiotics can help upregulate the genes linked to myelination and myelin plasticity (86).

Prebiotic-rich foods include sweet potatoes, carrots, onions, asparagus and squash. These foods are included in my free grocery shopping guide and you should try to eat them as much as possible.

To increase probiotic intake, you can take Optimal Biotics, which is a premium probiotic supplement that improves mental health.

I also like to drink kombucha and eat fermented foods regularly.

Check out this article to learn more about probiotics and prebiotics, and how you can use them to improve your brain function.

28. Reduce Exposure to Electromagnetic Fields (EMFs)

“I have no doubt in my mind that, at the present time, the greatest polluting element in the Earth’s environment is the proliferation of electromagnetic fields.” - Dr. Robert Becker, Nobel Prize nominee and author of The Body Electric: Electromagnetism And The Foundation Of Life

You won't hear many people talk about this but it needs to be acknowledged.

An increasing amount of research is showing that electromagnetic frequencies emitted from Wi-Fi, laptops, and cellphones can negatively affect the brain and produce widespread neuropsychiatric effects including depression (59). 

It’s an inconvenient truth that needs to be talked about, rather than downplayed, ignored and dismissed.

Some people are more sensitive to them than others. I’m one of them. 

Two environmental doctors told me that I’m sensitive to environmental radiation, and some of my symptoms can be traced back to EMF hypersensitivity. It's likely why I benefited so much from neurofeedback, as EMFs can affect brainwaves (74-78). 

I suspect a lot of people are dealing with the same problem. 

This research paper explains that there is an association between EMF exposure and myelin deterioration, which may account for many of the symptoms that people with EMF hypersensitivity experience (58).

So if you’re trying to rebuild myelin, it’s a good idea to limit your exposure to EMFs.

How do you that?

Here are some initial steps you can take:

• Get an EMF meter to determine your exposure. I use this one. It's the best option that is currently available. It measures electric, magnetic and radiofrequency fields. It's like having three meters in one.

• Put your phone on airplane mode when you’re not using it. Or use a radiation-blocking phone case such as Safe Sleeve. I did a lot of research into radiation-blocking cases and Safe Sleeve is the best on the market. They are manufactured with materials that have been 3rd-party tested to block 99.9% of radiation coming off a cell phone.

• Turn off Wi-Fi at night while you’re sleeping.

• If you have a laptop, don’t touch it. Use a wired keyboard and wired mouse instead.

• Supplement with the herb Rhodiola. It has radioprotective effects (60-62).

This is just the tip of the iceberg. There are many other steps you can take, and I plan on writing more about this soon because it isn’t discussed enough.

This may seem like “woo-woo” but it’s a real issue. And I suspect it will eventually become one of the biggest issues of our time.

Conclusion

You don’t have to let your brain deteriorate over time. 

You have the power to maintain it and rebuild the myelin within it. 

Overall, the above 28 steps can help your body regenerate myelin. They have really helped me.

I hope you implement some of them into your daily life and you notice your brain functions more optimally.

How to Protect Your Brain from Blue Light

Overcoming brain and mental health issues isn't just about nutrition and supplementation. 

It's also about light.

Chronic exposure to artificial blue light is a risk factor that is often overlooked. 

This post talks about how you should be striving to reduce your blue light exposure as much as possible throughout the entire day (unless it’s naturally coming from the sun). 

We're getting way too much blue light nowadays, and it’s taking a toll on your brain and mental health. 

And if you’re interested in learning more about light, I recommend the book Light: Medicine of the Future by Dr. Jacob Liberman. 

What Is Blue Light?

Light is part of the electromagnetic spectrum. 

Our eyes can only see light that falls within a small range of the electromagnetic spectrum, called "visible light". The human eye is not capable of "seeing" radiation with wavelengths outside the visible spectrum. 

Visible light corresponds to a wavelength range of approximately 400 to 700 nanometers (nm). Each visible wavelength is represented by a colour. Blue light is defined as having a wavelength between 450 and 495 nm. This short wavelength means that blue light is a type of high-energy visible light (25). 

Blue light is emitted from energy-efficient fluorescent and LED bulbs, and electronics such as computers, smartphones, tablets, and televisions. Obviously, these indoor man-made sources of blue light are on the rise, and we’re being exposed to more blue light in our environments than ever before (26). 

Why Artificial Blue Light Is Bad for Your Brain and Mental Health

I’ve been learning more and more that it’s best to limit your exposure to artificial blue light all day long, and not just at night. 

It’s important to note that there’s a big difference between artificial blue light and natural blue light from the sun. 

During the day, exposure to full-spectrum sunlight – which naturally contains some blue light –is actually beneficial and necessary for resetting your circadian rhythm.

The blue light from the sun is also balanced with other colours of light, such as red, green, infrared, and ultraviolet light.

But our devices and artificial lights have five times the amount of blue light than you would get from the sun. 

In the past, our ancestors would have been exposed to blue light from the sun only, and they weren’t exposed to blue light at night. 

But today, we shield ourselves from full-spectrum natural sunlight, and live indoors with excess artificial blue lighting all day long. 

And this is having brain and mental health consequences.

What The Experts Are Saying

An increasing number of researchers, doctors and health organizations are speaking out about this. 

Dr. Jack Kruse, MD, a neurosurgeon and author of the book Epi-Paleo Rx, and speaks passionately about the risks of blue light. He argues that attending to your light environment is more important than food. 

Dr. Alexander Wunsch, another physician and researcher in the field of photobiology, explains that artificial LED lights have an excess of blue light, and not enough red light, and this creates reactive oxygen species (19):

“We don’t have this kind of light quality in nature. This has consequences. The stress has consequences in the retina; it has consequences in our endocrine system.”

— Dr. Alexander Wunsch

Even the American Medical Association is speaking out about this issue.  Last June, they released guidelines on how to reduce the harmful human and environmental effects of high-intensity LED lighting.

They point out that the energy-efficient LED lighting adversely suppresses melatonin at night, has a “five times greater impact” on sleep rhythms than conventional lighting, and widespread implementation of this lighting will lead to sleep problems and other conditions related to poor sleep.

“Despite the energy efficiency benefits, some LED lights are harmful.”

— Dr. Maya A. Babu, AMA Board Member

There is lots of research to support these claims and concerns. 

Researchers have discovered photoreceptors (light-sensitive cells) in our eyes that track the amount of blue light we're exposed to throughout the day. These photoreceptors communicate with areas of your brain that affect your mood, emotions and circadian rhythm (20-22). 

It’s also well-established that blue light at night sends a signal to your body that it’s daytime, which increases the amount of time it takes to fall asleep and reduces the quality of your sleep. It does this by significantly suppressing the production of melatonin, your body’s sleep hormone (27-34).

Melatonin is also an antioxidant that protects your brain and increases mitochondrial function. So chronically low melatonin can lead to lower mental energy and neurodegeneration (35-37). 

In my experience, if your circadian rhythm is thrown off and you’re not sleeping well, it's very hard to be completely healthy and emotionally balanced.

Studies show that exposure to blue light at night is significantly associated with depression (23). 

Other research has found that “higher nighttime light intensity” leads to lower melatonin levels, which contributes to depression and cognitive impairment (24). 

But luckily there are ways to protect yourself.

Let’s get into what you can do to shield yourself from the negative effects of artificial blue light. 

1. Use Software That Blocks Blue Light

Installing software that prevents blue light from being emitted from your technology is another cheap and straightforward action you can take to protect yourself from excess blue light.

My number one recommendation is to install the program Iris on your computer. You can download it here. 

Iris automatically alters the colour temperature of your screen as the day goes on, removing the blue wavelengths after sunset.

The standard setting only removes blue light in the evening, but you can change the settings so that it blocks out blue light all day long. That’s what I do now. 

Iris takes care of your computer, but what about your phone? 

Last year, Apple released Night Shift with its iOS 9.3 update to reduce the amount of blue light emitted from the iPhone. You can learn how to activate this on your iPhone here. I have Night Shift turned on all throughout the day. 

You can also install Twilight if you have an Android device.

2. Wear Blue-Light-Blocking Glasses

It's becoming increasing clear that one of the simplest and least expensive ways to support your brain, promote healthy sleep, and lower your risk of chronic mental disease, is to wear blue-light-blocking glasses not just at night, but anytime you are exposed to artificial lighting.

I own multiple pairs of blue-light-blocking glasses myself.  

Research shows that wearing blue-light-blocking glasses improves sleep quality and mood (1). 

Other studies show that wearing blue-light-blocking glasses in a bright room or while using blue-lit technology maintains normal melatonin levels at night (2-4). 

Researchers have also found dramatic improvements in insomnia and mood in about half of bipolar patients who wore blue-blocking glasses (5). 

People with bipolar disorder who wore blue-blocking glasses from 6 p.m. to 8 a.m. for seven days had significant improvements in symptoms of mania compared to those who wore clear glasses. These benefits kicked in after just 3 days (6-7). 

I used to work on a computer in an office with lots of artificial fluorescent lighting shining down on me. 

At that time, I would wear these Gunnar computer glasses. These glasses have a light-yellow tint and are somewhat stylish. They significantly reduced the amount of blue light that I was exposed to throughout the day, which reduced fatigue and eye strain. 

They are like the opposite of sunglasses - I wore them inside when I was exposed to artificial blue light, and took them off when I went outside.

Gunnar Optiks has a wide-range of computer and gaming glasses to choose from through Amazon. 

If you work under blue light all day, it’s also a good idea to wear long sleeves because your skin also absorbs the blue light. Shielding it from your eyes is the priority though.

At home in the evening, I wear these orange-tinted Uvex glasses as soon as it’s dark outside. They eliminate all blue light, but aren’t stylish at all, so you’re better off wearing them inside and not out in public.

I also just ordered these red glasses, as they block out both blue and green light. Green light has been shown to stunt the release of melatonin, but not nearly as much as blue light. If you don’t have blue-blocking glasses yet, get the red ones. 

You can also get BluTech prescription lenses for the daytime but I haven’t done that for myself yet.

3. Increase Your Exposure to Red and Infrared Light

“Blue light causes reactive oxygen species in your tissue, and this stress needs to be balanced with near-infrared light that is not present in LEDs.”

— Dr. Alexander Wunsch

If you’re exposed to too much blue light, you need to make up for it later by exposing yourself to more red light.

One of the reasons red and infrared light supports brain and mental health is because it combats the effects of blue light. 

Ideally, we would simply be exposed to the sunlight throughout the day, which has a healthy balance of both blue and red light.

But unfortunately, we live in the modern world, and it’s not possible to live outside all day like our ancestors, even though our bodies still expect us to. 

I work in an office environment with lots of blue light, and no red and infrared light.

So to balance out my excess blue light exposure during the day, I use a number of different LED devices and bulbs in the evening that emit red and infrared light. 

As I’ve discussed before, I use this device on my head and thyroid. It has LEDs that emit red and infrared light. 

But what I haven’t mentioned before is that I also have this infrared bulb shining in my bedroom and this red bulb in my bathroom. I use them to light up my apartment, particularly at night.

Infrared saunas are another excellent way to expose yourself to infrared light. Check out my post about the benefits here. 

“Penetrating red light is possibly the fundamental anti-stress factor for all organisms. Old observations such as Warburg’s, that visible light can restore the activity of respiratory pigments, showed without doubt that visible light is biochemically active. By the 1960s, several studies had been published showing the inhibition of respiratory enzymes by blue light, and their activation by red light. The problem to be explained is why the science culture simply couldn’t accept crucial facts of that sort.”

— Dr. Raymond Peat

I find that doing all of this increases my energy and mood.

This may all seem strange but it works, and there is plenty of evidence to support it. 

In fact, red light therapy has been around for over 100 years. In 1910, Dr. John Kellogg published a book, titled Light Therapeutics, in which he recommended light therapy for a number of different diseases, including chronic fatigue.

Research shows that high-intensity blue light is bad for your mitochondria, while red light enhances mitochondrial function (15-18). 

I even found a study that clearly shows that red LED light protects animals from fake artificial blue light (14). 

And here is a spreadsheet that compiles a lot of the research showing that red and infrared light can help treat many different diseases, including depression, anxiety, traumatic brain injury, stroke, Parkinson's disease, Alzheimer's disease, multiple sclerosis, hypothyroidism, acne and chronic pain. 

Overall, blue light triggers oxidative stress in your cells, while red light repairs and regenerates your cells. Blue light is the equivalent to eating junk food, while red light is like eating healthy food. Staring at your smartphone all day and night is like eating McDonalds, while shining red light on yourself is like eating more vegetables. If you eat too much junk food, you might make up for it later by eating healthier and exercising. But with blue light, you need to make up for it by absorbing more red light. That’s what I do, and I hope it helps you too. 

4. Sleep in a pitch black room

Making sure your bedroom is as dark as possible while you sleep is another step you can take.  

Light can penetrate your eyelids, so simply closing your eyes is not enough. 

Even small amounts of light can reduce your melatonin production and disrupt your circadian rhythm. Exposure to room light during sleep has been shown to suppress melatonin by more than 50 percent (8). 

I completely black out my room with black-out curtains.

Another option is to wear a sleep mask. 

However, it’s important to note that your skin also has photreceptors and can sense light in your environment (9-11). 

So it’s optimal to just black out your entire room with curtains, especially if you have LED streetlights outside your house. 

Electronics should also be unplugged so that your room is completely dark. 

If you do these things, you’ll notice a profound difference in your sleep and brain and mental health.

5. Vitamin E and N-Acetyl-Cysteine (NAC)

Vitamin E and N-Acetyl-Cysteine (NAC) are two nutrients with antioxidant effects. 

One study found that NAC protects against the cellular damage induced by blue LED light (38). 

Perhaps this is one of the reasons NAC helps people who struggle with mental illness. 

Another study found that a combination of vitamin E and NAC significantly reduced blue-light-induced levels of reactive oxygen species (39). 

Both NAC and Vitamin E are included in the Optimal Antiox supplement.

6. Lutein and Zeaxanthin

Lutein and zeaxanthin are two more antioxidants that are found in your eye that may be able to protect you from the detrimental effects of blue light.  

Both zeaxanthin and lutein cannot be made by your body, so you must get them from food or supplements. They are found in green leafy vegetables, orange and yellow-coloured fruits and vegetables, and egg yolks. 

Together, these antioxidants can reduce free radicals before they cause damage and help your body better handle excess blue light. Researchers have found that they “absorb a broader spectrum of high-energy blue light, which offers greater protection of retinal tissue” (12, 13). 

You can also take them together as a supplement. 

Conclusion

Nutrition is important. But it's not the be all and end all.

Light is just as important.

Overall, you should aim to limit your exposure to blue light, both during the day and evening. 

Humans evolved getting a full spectrum of light throughout the day, not overwhelming amounts of artificial blue. 

Excessive blue light from LEDs and electronic screens can contribute to illness by triggering an overproduction of reactive oxygen species and decreasing your body’s production of melatonin.

But with the above modifications, you can significantly reduce the amount of blue light that enters your eyes and affects your brain and mental health.

13 Proven Ways Saunas Can Improve Your Mental Health

When it comes to improving your mental health, some of the simplest strategies can have a huge impact.

Using a sauna regularly is one of them.

Infrared saunas in particular are becoming increasingly popular, and for good reason. 

They have a number of brain and mental health benefits, as discussed in the book Sauna Therapy by Dr. Lawrence Wilson.

However, you don’t necessarily need an infrared sauna to experience health benefits. Even traditional saunas – available at most public gyms, spas and health centres – have a number of beneficial cognitive and psychological effects. 

Once you start using a sauna, you should listen to your body to determine how much time you should spend in it. Start out slowly and increase the length of your sessions over time. Also make sure to drink lots of water before and after each session, and never consume alcohol in combination.

Read on to learn about the 13 ways traditional and infrared saunas can improve your brain and mental health.

1. Saunas Improve Mood and Reduce Depression

Saunas can really help people that struggle with depression.

Lots of research shows that they can make you feel euphoric. Saunas are somewhat stressful on the body, so your brain produces and releases more euphoric hormones to deal with it (53-55).

And these changes appear to be semi-permanent (56). 

So if you use a sauna regularly, you'll end up being consistently happy. 

Dr. Jeffrey Lieberman, MD, has completed two studies in which he had people with major depression sit in an infrared sauna.

In his first study, the participants had just one infrared sauna treatment and it reduced their symptoms by about 50%.

In his follow-up study, he found that a single session caused a rapid and powerful antidepressant effect, and the benefits continued for six weeks, which was unexpected. 

He concluded that whole-body hyperthermia holds promise as a safe, rapid-acting, antidepressant treatment with a prolonged therapeutic benefit (57-58). 

Other researchers have looked at the effects of infrared sauna therapy on mildly depressed patients with fatigue, appetite loss, and mental complaints. They found that sauna treatment significantly increased their appetite and reduced their mental complaints (59). 

Whole-body heat therapy has also been shown to reduce depression in cancer patients (60-61).

And other research shows that sweating increases mental satisfaction and energy (62). 

2. Saunas Reduce Anxiety and Stress

Not surprisingly, saunas can also reduce stress and anxiety.

Several studies have shown that regular sauna use lowers levels of cortisol, your body’s main stress hormone (49-52). 

In one study, researchers found that using a sauna can reduce both state and trait anxiety (48).

And other research shows that sweating increases relaxation, and reduces feelings of frustration and anxiety (62). 

Here are 21 other ways to reduce cortisol and increase your resilience to stress.

3. Saunas Increase Beta-Endorphins, Relieve Pain and Help Treat Fibromyalgia

Beta-endorphins are pain-relieving compounds that originate within your body. 

Your brain produces and releases these natural painkillers during times of strenuous exercise, emotional stress and pain.

Since saunas are a stressor, the release of endorphins are increased when you spend time in one.

Several studies have shown that heat stress and heat exposure in a dry sauna cause a significant increase in beta-endorphin levels (28-32). 

This may explain why research shows that sauna therapy can lessen the pain experienced by patients with fibromyalgia, a chronic syndrome characterized by widespread pain with tenderness in specific areas.

In one study, people with fibromyalgia experienced a 33 to 77 per cent reduction in pain after using an infrared sauna regularly. Six months after the study was done, the participants still reported a 28 to 66 per cent reduction in pain (35). 

Other researchers have found the same thing and concluded that infrared sauna therapy is effective for the treatment of fibromyalgia (33-34). 

Another way to relieve pain is by taking DL-Phenylalanine. It’s an amino acid that inhibits the breakdown of endorphins. I previously wrote about it here.

4. Saunas Increase Brain-Derived Neurotrophic Factor (BDNF)

Brain-derived neurotrophic factor (BDNF) is a naturally-occurring protein in the brain that lowers your risk of mental disease and improves your mood. It does this by protecting and repairing your brain cells and increasing the growth of new brain cells. Many researchers consider it a natural antidepressant because it can reduce anxiety and depression (5-13, 15).

Research suggests that if you struggle with mental illness, you likely have reduced levels of BDNF. But luckily, there are ways to boost it.

Using a sauna is one of the ways. 

Research shows that heat exposure increases the expression of BDNF (14). 

I previously provided 21 other ways to boost BDNF in this post. 

5. Saunas Increase Norepinephrine Levels and May Help Treat Attention Deficit Hyperactivity Disorder (ADHD)

Norepinephrine, also called noradrenaline, is a hormone and neurotransmitter in the brain that can help with focus and attention.

Numerous studies have found that sauna use significantly increases norepinepherine levels (39-42). 

In one study, women spent 20 minutes in a sauna, two times each week, and researchers witnessed an 86% increase in norepinephrine (43). 

In another study, men that stayed in a sauna until exhaustion increased their norepinephrine levels by 310% (44-45). 

Besides increasing norepinephrine, heat stress also increases your body’s ability to store norepinephrine for later release (46). 

Medications that increase the reuptake norepinephrine are often prescribed to people with ADHD, so researchers believe that sauna therapy should be considered as an alternative treatment (47). 

6. Saunas Encourage the Growth of Myelin

Myelin is a fatty, white substance that wraps around the end of many nerve cells. It forms an electrically insulating sheath that increases nerve condition speeds.

In other words, it allows your brain to send information faster and more efficiently, making it absolutely essential for the optimal functioning of your nervous system.

Heat stress increases prolactin, a hormone that promotes the production of myelin (16-19). 

In one study, researchers had healthy young men stay in a sauna until they were exhausted, and they reported a 10-fold increase in prolactin (20-11). 

In another study, women spent 20 minutes sauna, two times each week, and researchers witnessed a 510% increase in prolactin (22). 

I previously provided 25 other ways to promote the growth of myelin in this post. 

7. Saunas Reduce the Risk of Dementia

Dementia is obviously a major concern today. 

It’s the third leading cause of death in the United States behind cardiovascular disease and cancer, and by 2050, it’s estimated that 13 million Americans and 160 million people globally will be affected by the disease (63).

There is currently a lack of effective treatment options, so simple tools to help with prevention are crucial.

It turns out that sauna therapy may be one of these tools.

Researchers tracked the health of more than 2,300 men in Finland for about 20 years. The men who used a sauna four to seven times each week had a 66 percent lower chance of developing dementia than men who used a sauna just once a week (64-68). 

“We have taken into account other lifestyle factors, like physical activity and socioeconomic factors. There is an independent effect of sauna.”

— Dr. Jari Laukkanen, Professor of Clinical Medicine at the University of Eastern Finland

I previously provided some other ways to reverse cognitive decline and dementia in this post. 

Intranasal insulin can also help. 

8. Saunas Reduce Psychological Symptoms of Anorexia

Anorexia nervosa, or simply known as anorexia, is an eating disorder characterized by a low weight, fear of gaining weight, a strong desire to be thin, and food restriction.

Researchers have examined the effects of sweating on anorexia and reported positive effects on hyperactivity, depression, and stress levels (27). 

9. Saunas Reduce Symptoms of Chronic Fatigue

Chronic fatigue syndrome is a complex, incapacitating illness. It affects millions of people around the world and may affect up to 4 million people in the United States alone. 

People struggling with this disorder not only have unrelenting fatigue lasting for 6 months or more, but also memory and concentration deficits, sleep disturbances, headaches, joint and muscle pain, and gastrointestinal and immune system dysfunction.

One study found that infrared sauna sessions significantly reduce fatigue in patients with chronic fatigue syndrome. It also significantly reduced their anxiety and depression (23). 

I've had some clients with chronic fatigue say that their doctor recommended they stay out of the sun and avoid exposing themselves to too much heat. But the above study didn't find any negative effects in chronic fatigue patients from regular infrared sauna sessions (23). 

Another study found that daily infrared sauna sessions dramatically improved symptoms of chronic fatigue syndrome, including fatigue, pain and sleep disturbances. The patients in the study didn’t improve with prednisolone, a steroid medication, but did improve with sauna therapy (24).

So if you struggle with chronic fatigue, infrared sauna therapy is definitely worth looking into. 

10. Saunas Reduce Tension Headaches

"Chronic tension-type headache" is a syndrome characterized by frequent headaches that occur more than 15 days every month. 

The intensity and duration of the headaches can be very distressing and disabling and affect a person's well-being.

But research shows that regular sauna use is a simple, self-directed treatment that is effective for reducing headache pain intensity (26). 

11. Saunas Help Eliminate Heavy Metals

Some of the benefits of sauna usage occur because of increased sweating. 

Many people don’t sweat very much, and this can cause problems because your skin acts as an important route of detoxification and helps you excrete heavy metals that are so prevalent in your modern environment. Common heavy metals in our environment include cadmium, arsenic, lead and mercury (36, 37). 

Lack of sweating may actually result in increased toxic load over time, which can negatively affect your brain and mental health.

Research shows that mercury poisoning from dental amalgam affects the mind and emotions and plays a role in the development of mental illness (1). 

But by sweating frequently in a sauna, you can enhance your detoxification pathways and help your body remove mercury (2, 4). 

In fact, studies show that high mercury levels can be reduced to normal levels by using a sauna repeatedly (3). 

Researchers have concluded that “sweat-inducing sauna use can provide a therapeutic method to increase elimination of toxic trace metals and should be the initial and preferred treatment of patients with elevated mercury levels” (38). 

“Sweating offers potential and deserves consideration to assist with removal of toxic elements from the body.”

— Researchers writing in the Journal of Environmental and Public Health

12. Saunas Increase Deep Sleep

Getting high-quality deep sleep is critical for optimal brain function and mental health. 

And using a sauna regularly is one way to improve it. 

Researchers in Finland report that sauna use is one of the factors that can result in deeper, more restful sleep (25). 

This sleep supplement contains magnesium and a number of other natural compounds that I’ve used over the years to deepen sleep.

But I work with my clients so that they can naturally maximize the quality of their sleep without so many supplements. We have free online workshop that talks about how you can work with us. You can register for the workshop here.

13. Saunas Support Thyroid Function

Your thyroid is a small butterfly-shaped gland located in your neck below your Adam’s apple, and lots of research shows that thyroid dysfunction can contribute to mental health problems. 

One of the main threats to the health of your thyroid is non-biological halogens. These include bromine, fluorine, chlorine, and perchlorate, which are often found in tap water.

Your thyroid doesn’t know the difference these halogens and iodine, a trace mineral necessary for proper thyroid function.

Your thyroid soaks up the halogens and uses them like iodine. By occupying iodine receptors, they inhibit the production of your thyroid hormones, and contribute to thyroid dysfunction.

But don’t worry – sauna use can help your body excrete halogens (69). 

The more you can excrete the halogens, the more your body will be able to use iodine to produce thyroid hormones.

I also recommend reducing your exposure by filtering your drinking and shower water. Brita filters aren't enough because they don’t remove fluoride. I use a Berkey water filter to make sure I’m drinking the purest water available. It filters everything out of the water. I also use this filter to remove chlorine from my shower water. 

I highly recommend getting a full thyroid panel done regularly.

Check out this post for more ways to support your thyroid. 

Conclusion

As you can see, saunas have a number of beneficial effects on the brain and can help you manage and overcome your mental health challenges. 

I’ve been doing a lot of research into saunas recently and have concluded that infrared saunas have additional benefits and are much more gentle and effective than the traditional “hot rock” saunas.

Unfortunately, most infrared saunas emit unsafe levels of electromagnetic fields (EMFs).

However, I did find a company that has a patent on low-EMF infrared saunas. Their saunas are also very well built and have a lifetime warranty. So I'm going to go with one of their saunas. You can get one here.

3 Foods You Should Avoid for Better Mental Health

Avoiding these three foods was one of the very first steps I took to improve my mental health.

I had a lot more energy, improved mood and reduced anxiety.

Unfortunately, about two months after cutting them out, I moved into a moldy house and suffered two really bad concussions. At that point, I had to look for even more advanced solutions.

But if you haven't done so already, I would strongly encourage you to try removing these three foods from your diet.

Doing so will likely improve your symptoms and calm your nervous system, making other therapies even more effective.

It’s harder to overcome trauma if you haven’t taken care of your physiology, as researchers have found that food allergies and sensitivities can trigger a wide range of emotional and mental health symptoms (110).

The problem with some foods is that they disrupt normal gut function and increase intestinal permeability (leaky gut syndrome). 

When this happens, small particles of food can leak into your bloodstream. Your immune system sees these food particles as foreign entities and attacks them, increasing inflammation throughout your body and reducing the integrity of the blood-brain barrier, which can cause or worsen mental health problems (4-6, 66-67). 

This is discussed in the book Gut and Psychology Syndrome: Natural Treatment for Autism, ADD/ADHD, Dyslexia, Dyspraxia, Depression, Schizophrenia by Dr. Natasha Campbell-McBride, MD.

If I eat any of these three foods by accident, I supplement with activated charcoal or bentonite clay. 

Activated charcoal and bentonite clay are potent natural treatments that can trap problematic proteins, toxins and chemicals, allowing them to be flushed out of your body. 

I notice I don’t feel as sick when I do this, and recover much more quickly.

Without further ado, here are three foods that I avoid as much as possible. 

1. Wheat

“Gluten sensitivity can be primarily, and at times, exclusively, a neurological disease.”

— Dr. Hadjivassiliou, MD, Professor of Neurology

Following a gluten-free diet has significantly improved my mental health (even though I didn’t have any terrible digestive issues). 

I completely cut it out seven years ago, and within a few weeks, I felt so much better mentally. 

I also lost a bunch of weight and my asthma disappeared. 

I haven't touched it again since.

The same thing happened to Mikhaila Peterson, the daughter of University of Toronto Professor Jordan Peterson.

She followed a gluten-free diet and her depression, fatigue, irritability and memory problems faded away, allowing her to come off her antidepressants.

Dr. Peterson made the same dietary changes and was able to reduce his medication by half. 

You can watch a video of them discussing it here. 

Unfortunately, the myth continues to spread that only people with celiac disease need to avoid gluten-containing food. That’s simply not true.  

Dr. Kenneth Fine, a pioneer in gluten intolerance research, has demonstrated that 1 in 3 Americans are gluten intolerant, and that 8 in 10 have the genes that predispose them to developing gluten intolerance (1-3). 

The benefits of cutting out gluten are also discussed in this book. 

So if you struggle with a cognitive or mental health condition, you owe it to yourself to follow a strict gluten-free diet for 30 days and see how you feel. You'll likely feel better.

For more than sixty years, reports in the scientific literature have linked wheat and gluten sensitivity to a variety of neurological and psychiatric conditions (75-81), including:

“A PubMed literature search (dates 1953–2011) located 162 original articles associating psychiatric and neurologic complications to celiac disease or gluten sensitivity. Thirty-six articles were located for seizure disorders, 20 articles for ataxia and cerebellar degeneration, 26 for neuropathy, 20 for schizophrenia, 14 for depression, 12 for migraine, and up to 10 articles each for anxiety disorders, attention deficit and hyperactivity disorder, autism, multiple sclerosis, myasthenia gravis, myopathy, and white matter lesions.”

• Schizophrenia (39-60)

• Depression (18-25)

• Autism spectrum disorders (30-38)

• Epilepsy and seizures (13-17)

• Dementia and cognitive decline (61-63)

• Anxiety (9-10)

• Attention deficit hyperactivity disorder (26-27)

• Cerebellar ataxia (69-72)

• Social phobia (11)

• Panic disorder (12)

• Bipolar disorder (28)

• Migraines (29)

Luckily, research shows that when people with these neurological and psychiatric disorders follow a gluten-free diet, there is a reduction in their symptoms. 

Many times, there is even a complete resolution in their symptoms. 

In one study, depressed patients who didn’t have digestive issues (like me) followed a gluten-free diet. Within 2-3 months, they experienced a reversal of their depressive symptoms (68). 

Researchers have also found that a gluten-free diet improves depression and reduces behavioural problems by increasing levels of l-tryptophan – the precursor to the neurotransmitter serotonin (64). 

Another study found a significant increase in serotonin and dopamine because of the removal of gluten (65). 

Clearly, there is more to gluten than celiac disease and digestive issues, and cutting out wheat is one of the first dietary steps I recommend to people who are striving to overcome mental health challenges. 

I understand that it's tough to cut out completely, but it’s worth a try because it may be all you need. 

“A grain-free diet, although difficult to maintain (especially for those that need it the most), could improve the mental health of many and be a complete cure for others.”

— Dr. Paola Bressan

Other than avoiding wheat, you should also avoid foods that contain barley, rye and spelt because they also contain gluten. Sauces, condiments and soups often contain it, so you should stay clear of almost all processed food. Even some medications can contain gluten. 

As discussed in the GAPS Diet book, the bacteria in our guts can determine the degree to which we are sensitive to gluten (73). 

So you should also try to increase the good bacteria in your gut. 

And as I mentioned earlier, I take activated charcoal or bentonite clay whenever I accidentally consume wheat and it minimizes the negative effects. 

2. Milk

"Milk, and all that comes from milk, increases melancholy." – Robert Burton, Anatomy of Melancholy

After childhood, many people lose the enzyme, lactase, required to digest milk.

And a lot of people who suffer from brain and mental health problems are allergic or sensitive to milk.

People are allergic or sensitive to two main components of milk – lactose and casein.

Casein is the milk protein. Lactose is the milk sugar. 

Like gluten, both lactose and casein can contribute to inflammation in the body and brain, contributing to mental illness.

Research shows that people with neuropsychiatric diseases – including schizophrenia, bipolar disorder, depression, anxiety, and autism – often have significantly elevated immune reactions to casein in milk, which corresponds with the severity of their mental symptoms. And their symptoms can be “improved substantially or even been cured completely” on a dairy-free diet (82-83, 85-91). 

Interestingly, casein has been shown to reduce the absorption of cysteine by 64% (92). 

Cysteine is an important amino acid for mental health. I previously discussed it here. 

It plays a role in the production of glutathione, your body’s master antioxidant, which protects your body from oxidative stress. And people with mental health problems often have high levels of oxidative stress (93-94). 

Therefore, milk may indirectly reduce glutathione levels and increase oxidative stress by preventing the amino acid cysteine from entering cells (92). 

Perhaps this is why so many people find benefit from supplementing with n-acetyl-cysteine. 

Folate is another critical nutrient for mental health, and milk has been shown to decrease the transport of folate into the brain (95). 

This makes sense considering that folate plays a key role in methylation, and other research has found that casein also reduces DNA methylation by 43% (96). 

Lastly, researchers have also discovered that high levels of lactose in the intestines can interfere with tryptophan metabolism and serotonin levels. They concluded that lactose malabsorption may play a role in the development of depression (84). 

All this being said, it seems that dairy affects everyone differently.

So you should try eliminating all conventional milk-based foods including ice cream, cheese and yogurt for 30 days. Then try adding it back in and examine how you feel.

It’s important to note that the milk in the grocery store is usually processed, homogenized, and pasteurized with distorted fats and denatured proteins. It’s not considered a whole food and I think everyone should avoid it. 

My free food guide still includes grass-fed, full-fat, organic dairy because it’s a healthy whole food and plenty of people can tolerate it just fine.

I personally choose not to eat any milk or dairy though because I still feel better without it.

In conclusion, here is Dr. Daniel Kalish’s take on dairy. He is the author of The Kalish Method: Healing the Body, Mapping the Mind: 

“People with sub-clinical gluten intolerance need to avoid pasteurized cow’s milk products. As the villi on the intestinal lining heal from a gluten free diet, most individuals will be able to tolerate raw or unpasteurized dairy products again in nine months to a year. In other people, there will be a more or less permanent sensitivity to dairy products. However, in the initial two months of eliminating gluten, it is absolutely required to avoid all milk dairy products, because they will inflame the intestine lining just like gluten does and prevent healing.”

— Dr. Daniel Kalish

3. Vegetable Oil

“The increased incidence rate of major depression since 1913 may be explained by a sharp increase in the rate of omega-6 PUFAs in the diet.”

— Dr. Michael Maes

The last food you should avoid or significantly limit is refined vegetable oil, including soybean, corn, safflower, sunflower, and canola oils.

They are highly unstable and oxidize very easily. 

Like gluten, vegetable oils are everywhere and hard to avoid because they’re included in most processed foods.  

These oils are also predominantly made up of omega-6 fatty acids.

This is a problem because most people eat way too many omega-6 fatty acids today, and not enough omega-3 fatty acids.  

Omega-6 fatty acids increase inflammation, while omega-3 fatty acids reduce inflammation.

An international panel of lipid experts says that the ideal dietary ratio of omega-6 to omega-3 is approximately 1 to 1. But these same experts estimate that the current ratio that people are consuming today is around 20 to 1 (97-101).

As I discussed before, omega-3 fatty acids can help prevent and treat mental disorders

Unfortunately, they are being outnumbered by the inflammatory omega-6 fatty acids in our food supply. 

Luckily you can combat this by staying clear of vegetable oils, supplementing with krill oil, and eating wild salmon regularly.

Not doing this can lead to mental health problems.

Dr. Raymond Peat, PhD, says that the sudden increase of vegetable oils in our food supply after World War II has caused many changes in our mental health:

“In 1980, experimenters demonstrated that young rats fed milk containing soy oil incorporated the oil directly into their brain cells, and had structurally abnormal brain cells as a result.”

Studies have also found a very strong correlation between vegetable oil consumption and violent behavior, including homicide (109). 

This graph shows data from one study, looking at omega-6 intake and homicide rates in five countries.

Dr. Stephan Guyenet, author of The Hungry Brain: Outsmarting the Instincts That Make Us Overeat, discusses this in more depth here. 

And it’s not just violent behaviour. 

There is a significant correlation between the severity of depression and the ratio of omega-6 to omega-3 fatty acids. Many researchers suggest trying to treat depression by reducing the ratio with omega-3 supplementation (106). 

Other researchers have found significantly lower levels of omega-3 fatty acids in the blood of patients with depression because of their higher omega-6 fatty acid intake (107). 

Too many omega-6 fatty acids have also been linked to increases in cortisol, your body’s main stress hormone (102-104). 

And elevated homocysteine levels – a known risk factor for mental health problems – has been associated with excess omega-6 fatty acids (108). 

I recommend checking out the Perfect Health Diet by Paul Jaminet and Shou-Ching Jaminet if you’re interested in learning more about the detrimental health effects of refined vegetable oils. 

Other Possible Food Intolerances

Be aware that you may be sensitive or intolerant to other seemingly healthy foods, and if so, they should be avoided to maintain good mental health. 

This is discussed in Brain Allergies: The Psychonutrient and Magnetic Connections by Dr. Willam Philpott, MD. 

For example, eggs are an incredibly nutritious and healthy food, but I’m personally intolerant to the egg whites, so I throw away the whites and just eat the yolks. 

It’s not a big deal though because the yolks are the healthiest part of the egg anyway.

But I originally figured this out by following an elimination diet.

You eliminate all possible food allergens and then add them back in one by one and see if you have a negative reaction.

You can learn more about it in this book. 

Some of the most common food allergens that could affect your mental health include:

• Eggs

• Soy

• Corn

• Nightshade vegetables

• Peanuts

• Tree nuts, like walnuts, almonds, pine nuts, brazil nuts, and pecans.

• Yeast

• Fish

• Shellfish

• Sulphites

If you struggle with mental health problems, you should cut them all out for at least 2 weeks. Then add them back in one by one and see how you feel. 

Eat each food a lot over the course of three days and monitor your reaction to each one. Sometimes negative symptoms can pop up a few days later. 

Conclusion

Unfortunately, the role of food in the development of mental health disorders is often overlooked by conventional psychiatrists and some psychologists. 

They hardly receive any training in nutrition and rarely consider food intolerances as a possible cause of mental health symptoms. 

Instead, psychiatric drugs are simply prescribed, which can lead to worse gut health, more symptoms and more medications. 

However, psychiatric drugs are necessary for many people. I completely understand that.

But if your mental health is failing, try eliminating gluten, dairy and refined vegetable oils and observe the effects. You may be surprised at how much better you feel.

Let’s spread the word that there is a link between nutrition and mental health!
